The present disclosure is directed to an endoscope and lens cleaning device assembly and, more particularly, to an endoscope including a lens cleaning device that is configured to clean a lens of the endoscope during an endoscopic surgical procedure at the surgical site.
During an endoscopic surgical procedure, surgical tools are inserted through small incisions in a patient to access an operative site within a body cavity. Typically, the body cavity is insufflated with an inert gas such as CO2 and an endoscope is inserted through one of the small incisions to allow a clinician, e.g., a surgeon, to visualize the surgical site. Visualization of the surgical site is critical to successfully performing all surgical procedures.
During a surgical procedure, it is common for a lens of the endoscope to become smudged and/or obstructed with debris and require cleaning. Typically, the endoscope is removed from the body cavity and the lens of the endoscope is manually wiped clean. However, removal of the endoscope from the body cavity during the surgical procedure causes a temporary loss of visualization of the surgical site, increases the time required to perform the surgical procedure, and may result in a loss of insufflation within the body cavity.
A continuing need exists in the surgical arts for a method and device to clean the lens of an endoscope within a body cavity during a surgical procedure.
One aspect of the disclosure is directed to an endoscope and lens cleaning device assembly including an endoscope having a tubular body, a visualization device including a lens supported on the endoscope, and a lens cleaning device. The tubular body defines a longitudinal axis and has a proximal portion and a distal portion. The visualization device is supported on the tubular body. The lens cleaning device is supported on the distal portion of the tubular body and includes an iris mechanism including a plurality of vanes. The vanes are movable between a first position in which the vanes are positioned radially outwardly of the lens of the visualization device and a second position in which the vanes cover the lens of the visualization device. Each of the vanes has a cleaning surface that is positioned to contact the lens of the visualization device as the vanes move between the first and second positions to clean the lens of the visualization device.
In embodiments, the lens cleaning device includes an actuator having a first end positioned adjacent the proximal end of the tubular body and a second end in contact with the iris mechanism, wherein the actuator is movable to cause movement of the vanes between the first and second positions.
In some embodiments, the actuator includes an actuator tube having a proximal portion, and a distal portion that supports at least a portion of the iris mechanism.
In certain embodiments, the proximal portion of the actuator tube includes a grip to facilitate movement of the actuator.
In embodiments, the actuator tube is rotatably supported in relation to the tubular body.
In some embodiments, the actuator tube is rotatably supported about the tubular body.
In certain embodiments, the iris mechanism further includes a support plate and an actuator ring, and the plurality of vanes is positioned between the support plate and the actuator ring.
In embodiments, the support plate is secured to the distal end of the tubular body.
In some embodiments, the actuator ring is secured to the distal portion of the actuator.
In certain embodiments, the actuator includes an actuator tube that is rotatably supported about the tubular body.
In embodiments, each of the plurality of vanes has a first end that is pivotably coupled to the support plate and a second end including a cam member.
In some embodiments, the actuator ring includes a plurality of cam channels, wherein each of the cam channels receives a respective one of the cam members of the plurality of vanes such that rotation of the actuator ring in relation to the support plate causes movement of the plurality of vanes between the first and second positions.
In certain embodiments, the tubular body defines a longitudinal bore that is dimensioned to receive a surgical device.
In embodiments, an irrigation channel is supported on the tubular body and has a distal end that is positioned to direct irrigation fluid onto the lens of the visualization device.
Another aspect of the present disclosure is directed to a lens cleaning device including an iris mechanism having a plurality of vanes, an actuator ring, and a support plate. The plurality of vanes is supported between the support plate and the actuator ring such that rotational movement of the actuator ring in relation to the support plate causes movement of the plurality of vanes between a first position in which the vanes define a central opening and a second position in which the vanes cover the central opening. Each of the vanes has a wiper surface that is positioned to contact a lens of a visualization device as the vanes move between the first and second positions to clean the lens of the visualization device.
Various embodiments of the presently disclosed endoscope and lens cleaning device assembly are described herein below with reference to the drawings, wherein:
The presently disclosed endoscope and lens cleaning device assembly will now be described in detail with reference to the drawings in which like reference numerals designate identical or corresponding elements in each of the several views. However, it is to be understood that the disclosed embodiments are merely exemplary of the disclosure and may be embodied in various forms. Well-known functions or constructions are not described in detail to avoid obscuring the present disclosure in unnecessary detail. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure in virtually any appropriately detailed structure.
In this description, the term “proximal” is used generally to refer to that portion of the device that is closer to a clinician, while the term “distal” is used generally to refer to that portion of the device that is farther from the clinician. In addition, the term “endoscopic” is used generally used to refer to endoscopic, laparoscopic, arthroscopic, and/or any other procedure conducted through a small diameter incision or trocar cannula assembly. In addition, the term “clinician” is used generally to refer to medical personnel including surgeons, doctors, nurses, and support personnel.

Although the support plate is shown in a position secured to the distal portion of the tubular body of the endoscope 12, it is envisioned that the support plate 34 can be secured to the vanes 38 and the actuator ring 36 such that the lens cleaning device 14 forms an integral cleaning device. In such a device, a proximal face of the support plate 34 may include an adhesive that engage with a distal face of the endoscope 12 when the lens cleaning device 14 is supported about the endoscope 12 to prevent rotation of the support plate 34 in relation to the endoscope 12 when the actuator tube 70 is rotated in relation to the endoscope 12.
Although shown as a tubular member, the actuator 30 can be in the form of any structure or device that can affect rotation of the actuator ring 36 in relation to the support plate 34 to cause movement of the vanes 38 between the first and the second positions shown in
The presently disclosed endoscope lens cleaning device is configured for intraoperative use and facilitates cleaning of a lens of an endoscope without having to remove the endoscope from a body cavity. The endoscope is configured to be received through a small diameter trocar/cannula assembly, e.g. 5 mm or 10 mm trocar-cannula assembly.
During an endoscopic surgical procedure, the lens 22 (
